FAREWELL, FRIEND

Demobilised after the war in Algeria, legionnaire Franz Propp tries to get army doctor Dino Barran to go to the Congo with him. But Barran feels he has to help the beautiful Isabelle Moreau, whose lover he accidentally killed in Algeria. She wants him to take a job in a big firm in Paris, where his assistant will be an attractive girl called Dominique Austerlitz, and over the Christmas break to secretly return some missing documents to the safe.

Propp, who has found work as a pimp, follows Barran into the building and overhears that there are also millions in wages in the safe. He wants the money, while Barran merely wants to fulfil his promise to Isabelle. After much arguing and fighting the two unwillingly co-operate and get the safe open, to find the money has been taken. They also find they are locked in the strong room with no light, air, food or drink. Escaping eventually through a shaft, they find a security guard shot dead. Successfully getting out of the building, they try to catch a flight at the airport but Propp is caught by the police. Despite intensive interrogation, he does not talk.

Meanwhile, Barran, who has persuaded Dominique to shelter him, offers to talk to the police. They follow him to the scene of the crime, where Dominique is to look for evidence of his innocence, when Isabelle appears with a gun. In a fracas she shoots a policeman, whereupon both girls are killed by a police machine gun. It was the two of them who had taken the money, killed the guard, and tricked Barran into being their fall guy.

After escaping the vault, Barran and Propp find themselves implicated in murder and robbery. Isabelle and Dominique are revealed as the true conspirators, resulting in a deadly confrontation where both women are killed by police.

The climax exposes the depth of the setup: Barran and Propp are mere pawns manipulated by those they trusted. Loyalty proves fragile, as the supposed allies are actually orchestrators of the crime. The ending lands a cynical note on trust, innocence, and manipulation, with the men surviving but thoroughly disillusioned by those around them.
